CJ40 Unit Costing Periodical Values

I am using CJ40 unit costing but my requirement is whenever we update the values here it need to be updated periodically same like we do in CJR2 for cost element planning.

I have observer that when we post the unit costing in WBS, it updates the table CKHS, CKIT, CKIS..etc but CKIP (Unit Costing: Period Costs Line Item) is not getting updates. Also CJ40 values do updates the RPSCO table with budget type: KEKP but it always update 1st period i.e. WLP01 column instead all 12 period columns.

Project System experts can you please advise how we can update the CJ40 values periodically (Updating CKIP table).
